As stated by the kinetic theory of gases, how does a molecule of an ideal gas move during the interval between two consecutive collisions?

1. Along a curved route
2. Along a straight-line path
3. With increasing speed due to acceleration
4. Along a circular path

Correct answer: Along a straight-line path

Solution

According to the kinetic theory of gases, molecules of an ideal gas move in straight lines between collisions, as they are considered to have no interactions except during these brief collisions.
